We have mentioned a little about kilograms and pounds yet but today we want to focus on a specific number of kilograms and pounds. This article is dedicated to conversion **30 kg to lbs**. If you are interested in this topic, keep reading.

Let’s start with some basic information about these two units before we move on to calculations. Both of them are units of mass but there are some differences between them.

**The kilogram** is a unit of mass used in a metric system, known as International System of Units (in abbreviated form SI). The symbol of a kilogram is kg.

Formerly, the definition of a kilogram was the mass of one litre of water. Nowadays the **official definition of a kilogram**** is**:

“**The kilogram, symbol kg, is the SI unit of mass.** It is defined by taking the fixed numerical value of the Planck constant h to be 6.62607015×10−34 when expressed in the unit J⋅s, which is equal to kg⋅m2⋅s−1, where the metre and the second are defined in terms of c and ΔνCs.”

The kilogram is used in science, engineering and also in everyday life, for instance, to measure human body weight.

The pound is used mostly in Imperial and the United States customary system. Sometimes it is also used in other systems. The most common is avoirdupois pound. The symbol of avoirdupois pound is lb.

**The pound** is defined as 0.45359237 kilograms. It can be divided into 16 avoirdupois ounces.

Like a kilogram, a pound is also used to measure, for instance, human body weight.

In this article we want to focus not only on **30 kg to lbs ****conversion** but also **30 lbs to kg**** conversion**.

Before we move on to a formula for **conversion kilograms into pounds** and pounds into kilograms, you need to know **how many pounds are in a kilogram** and **how many kilograms are in a pound**. So have a look:

- 1 kg = 2.20462262 lbs,
- 1 lb = 0.45359237 kg.

These basic information are needed to convert **30 lb into kg**. So let’s move on to the more practical part of this article.

Let’s begin with calculations. Firstly, we want to focus on conversion from kilograms to pounds.

The formula for kg to lbs calculation is down below:

**Number of kilograms * 2.20462262 = the result in pounds**

Let’s make a calculation. **How many pounds in 30 kilograms****?** Multiply 30 by 2.20462262 to get the result. It gives 66.1386786. So **30 kilograms is equa**l 66.1386786 pounds. You can also round off the result, for instance, to two decimal places. The final result is equal 66.14 pounds.

You can also make calculations using a formula in shorter form. We gave it down below:

**Number of kilograms * 2.2 = the result in pounds**

If you use this formula, your calculations will be so much easier but you have to remember that the result will be not so accurate.

Let’s try this formula and see if the difference between final results will be significant.

**How many pounds in 30 kilograms****?** Multiply 30 by 2.2. It gives 66 pounds.

In our previous example, when we used a full formula, the result was 66.14 pounds after rounding off. As you can see, the difference is not significant. So if you do not need an accurate result, using a shorter formula will be sufficient.

Now you know how to calculate **30 pounds in kilograms** so we want to show you the results in two charts. In first chart we will show you the result calculated using a full formula. Have a look:

Kilograms (kg) | Pounds (lb) |

30 | 66.1386786 |

In the second chart we want to show you the result calculated using a shorter form of a formula. Let’s see:

Kilograms (kg) | Pounds (lb) |

30 | 66 |

Now try to make reverse calculations. It means **calculations from pounds into kilograms**.

The formula for **lb to kg calculation** is down below:

**Number of pounds * 0.45359237 = the result in kilograms**

So try to calculate **30 kilograms to pounds**. Multiply 30 by 0.45359237. It gives 13.6077711. After rounding off to two decimal places, the final result is equal 13.61 kilograms.

In this case you can also use a shorter form of a formula to make your calculations easier. We gave it down below:

Number of pounds * 0.45 = the result in kilograms

So try this formula and see the difference between results. **How many kilograms in 30 pounds****?** Multiply 30 by 0.45. It gives 13.5 kilograms.

In the previous example our result was equal 13.61, in this example, using the shorter formula, our result is equal 13.5. As you can see, there is the difference but it is not big. So if you do not need an accurate result, you can use a shorter form of a formula.

Now we want to show you the results in two tables, as in the case of **conversion 30 kg to lbs**. In the first table is the result calculated using a full form of a formula. Have a look:

Pound (lb) | Kilogram (kg) |

30 | 13.6077711 |

In the second chart is the result calculated with shorter form of a formula. Let’s see:

Pound (lb) | Kilogram (kg) |

30 | 13.5 |
